Careful statistical analyses indicate that the measured traffic traces from live packet networks often contain non-stationary effects like level shifts or polynomial trends. In these cases several popular tests for long-range dependence can result in wrong conclusions and unreliable estimate of the Hurst parameter. In this paper both analytical and simulation investigations of the implications ...

The problem of maintaining gauge invariance when truncating the two particle irreducible (2PI) effective action has been studied recently by several authors. Here we give a simple and very general derivation of the gauge dependence identities for the off-shell 2PI effective action. We consider the case where the gauge is fixed by an arbitrary function of the quantum gauge field, subject only to...

A set of polynomials in noncommuting variables is called locally linearly dependent if their evaluations at tuples of matrices are always linearly dependent. By a theorem of Camino, Helton, Skelton and Ye, a finite locally linearly dependent set of polynomials is linearly dependent. In this short note an alternative proof based on the theory of polynomial identities is given. The method of the ...

This work focuses on the study of the dynamic behavior and lattice size dependence of the surface root-mean-square slope in a porous thin film deposition process taking place on a triangular lattice. The simulation results indicate that the expected mean slope square reaches quickly a steady-state value and exhibits a very weak dependence with respect to lattice size variation. The simulation f...

The rotational angular momentum (spin) dependence of the binary scattering amplitude operator is investigated for elastic collisions of homonuclear diatomic molecules with monatomie and diatomic particles. Starting point is a formal expansion of the jT-matrix (and consequently of the scattering amplitude) with respect to the nonsphericity parameter e which essentially measures the ratio of the ...

We prove that, for generic systems of polynomial differential equations, the dependence of the solution on the initial conditions is not differentially algebraic. This answers, in the negative, a question posed by L.A. Rubel.

The maximal sniff generated mouth and transdiaphragmatic pressures of six healthy volunteers (three women and three men) were measured at various lung volumes between residual volume and 95% of total lung capacity. At residual volume the mean (SD) maximum transdiaphragmatic pressure was 163 (18) cm H2O (1 cm H2O = 0.0981 kPa). With increasing lung volume the maximum pressures generated declined...

We study the location of the partition function zeros in the complex β plane (Fisher’s Zeros) for SU(2) lattice gauge theory on L4 lattices. We discuss recent attempts to locate complex zeros for L = 4 and 6. We compare results obtained using various polynomial approximations of the logarithm of the density of states and a straightforward MC reweighting. We conclude that the method based on a c...

Nonabelian gauge theories with a generic background field Aμ in nonlinear gauges due to Delbourgo and Jarvis are investigated. The Aμ-dependence is completely determined by the help of a linear differential equation which obtaines from the Kluberg-Stern-Zuber and the Lee identity. Its integration leads to a relation between the one-particle irreducible vertex functional in the background field ...

The paper regards the classical Evans price equilibrium model in free product market aspect of regarding opportunities for expanding (modifying) given that is aimed at perfecting accuracy its mathematical formulating. As an criterion, we have chosen a summary quadratic deviation calculated indices from ones. One approaches modifying basic suggesting there linear dependence between function and ...
